Nickel Silicon Alloy (NiSi)-Powder

Characteristic

NiSi is an austenitic nickel-silicon alloy. It can be used as the negative extreme of an n-type thermocouple. It has good thermoelectric stability above 1000 degrees C and has better antioxidant properties than E,J and K thermocouples.

The Nickel-Silicon alloy parameters:

Chemical composition: Si:4.3%, Mg:0.1% Ni

Density: 8.585 g/cm3

Resistance: 0.365 ohm mm2/m

Resistance temperature coefficient (20-100 degrees c): 689x10-6 /k

Thermal expansion coefficient (20-100 degrees c): 17x10 -6 /k

The thermal conductivity(100 degrees c): 27xwm-1 K -1
